I have been using 10 gauge zip cord for decades, since I first heard a
shop selling junk speakers by hooking up AR3s with "speaker wire" for
comparison.
It's easy enough to calculate the impedance of any length of
standard-gauge wire. That yields the damping factor for speaker
resonances since it is almost always far more than the output impedance
of a modern amplifier. Said damping factor then goes into classic
expressions for the Q of the tuned circuit which is the electrical
aspect of a speaker.
In short, run a few feet of high-impedance wire to turn your
high-quality speakers into a boom box.
